Reminder to configure earlyOOM and or watchdog on your servers... In case some fuckass service decides to leak memory at GBytes per minute and lock up a remote machine with no kvm 💀

cgroups can set a limit on the total memory that can be assigned to a group of processes, then kill any that request more. mkdir /sys/fs/cgroup/memory/my_cgroup echo $PID >> /sys/fs/cgroup/memory/my_cgroup/cgroup.procs echo $MAX_MEMORY_IN_BYTES > sys/fs/cgroup/memory/my_cgroup/memory.limit_in_bytes
